Title:	SOME METHODS TO TREAT CAPACITY ALLOCATION PROBLEMS
Author:	A. IDRISSI
Source:	Journal of Theoretical and Applied Information Technology pp 141 - 158 Vol 37. No. 2 -- 2012
Abstract	The Constraint Satisfaction Problems (CSP) are proven more and more promising to model and solve a large number of real problems. A lot of approaches using constraint reasoning have been proposed to solve search problems. Our contributions here consist to propose a modeling of Capacity Allocation Problem of an airport (CAP) in the form of a CSP. This modeling produces a model which we call CSPAC. Then, we generalize this model to the fixes of the airport and call the new model GCSPAC. Thereafter, we describe an approach combining the branch-and-bound algorithm and local search to solve both CSPAC and GCSPAC. This method allows assisting the airport managers to regulate the arrival/departure predicted demands and to optimize the utilization of the available capacities of a terminal. Finally, we expose some experimental results showing the utility of our different approaches.

Author:	A.I. ADAMU, T. MANTORO, M.A SHAFII
Source:	Journal of Theoretical and Applied Information Technology pp 159 - 170 Vol 37. No. 2 -- 2012
Abstract	This paper presents the mechanism of multi-user navigation interaction in real-time as a high-priority objective in improving mobility services efficiency and effectiveness, and investigate the support of three-dimensional representation in mobile device in aiding interactive navigation in an unknown environment. The paper is based on the fact that the use of 3D representation in mobile device is more intuitive than the conventional 2D representation. Unfortunately, Mobile devices are small devices, and that is why there are mobile, as a result, 3D dataset in mobile device might overload its performance. Even though, certain techniques were seen in many research on tackling this problems, yet, when it comes to the navigation aid the predominant 3D mobile navigation system are not interactive in real-time, that is a user will not be aware of other users while on-the-go and both using mobile navigation aid in the same environment. We provide an interactive navigation techniques for finding the shortest path to a desire destination and also been able to interact with an (agent if it’s another user) or (object in terms of point or destination) in real-time with the help bi-A* pathfinding algorithm and voronoi diagram. The use of bi-A* Algorithm is to establish a forward and backward search for a destination or a position of users, while the use of voronoi diagram is to establish points and region within the navigation environment. The result of our finding indicate that information in three-dimension for navigation aid in mobile device is more intuitive and experimental result shows that multi-user interaction with support of 3D representation in mobile devices helps in aiding number of user going around within an environment an been able to be aware of their movement in real-time. This approach is unique because it provides visualization of 3D representation (map) in mobile devices’ which assists users to navigate interactively.

Abstract	Sports are not only means of attaining physical fitness, rather nowadays have become a scientific field where statistical analysis play a vital role to overcome one’s weaknesses and exploit that of opponents’. Similarly, in Cricket, bowling in the right areas has always been a headache for the bowlers and the coaches alike, not because bowlers are not accurate enough, but because the ‘right areas’ vary greatly according to the weather, pitch conditions, field placing, ball condition etc. Above all, the strengths and weaknesses of each batsman varies. With so many variables to consider while bowling, it is hard for a coach to figure out which area is the right one, leaving the bowler with no option other than to stick to the basics. We propose Genetic Algorithms to help the bowler in selecting the right areas to bowl to a particular batsman hence solving this rather difficult coaching problem in a straightforward manner.

Abstract	Disaster is an old challenge to the human society, which is continuously presenting new threats to society and its way of life. Thus, it is important for us to find ways to help mitigate these threats and to provide the society with better solutions to cope with disaster. Over the past decades, disasters have also caused damaged to telecommunication infrastructure, and thus affecting computer networks. In the world that now depends heavily on Internet and computer-based communication, damaged to computer networks will cause a lot of problems to any countries. Most of the work that address the issue of disasters and computer networks role focuses on reestablishing services after the impact. Although this is important, much research is needed in anticipating their impact of disasters on computer networks. This paper aims to propose a model for evaluating changes in Malaysian computer networks traffic caused by a regional disaster in some other part of South East Asia. The model deals with the possibility of a disaster that triggers additional disasters that may lead to more network failure.

Author:	SANTHI.B,RAM KUMAR.K
Source:	Journal of Theoretical and Applied Information Technology pp 217 - 223 Vol 37. No. 2 -- 2012
Abstract	In this modern world ATM is being used by many of us. The security that is being currently used for ATM indeed has a few backdoors and it can be improved further. For the same reason biometric verification were introduced. But even the biometric system does not seem to be completely reliable and hence a contingency plan is needed in order to prevent catastrophes. Objective of this paper is to provide enhanced security to ATM by enhancing the already proposed biometric system and making it still secured by PII[Personal Identification Image] process. So a detailed study on various existing biometric systems is studied and also its limitations are listed. This paper proposes a novel method to meet out the challenges and strengthen the security mechanism. In the proposed security algorithm two phases are defined. These two phases provide two tier security and there by increases the security of ATM machine.

Abstract	The sharp growth of online-systems and vast availability of high quality data lead to information overload, increasingly very difficult for the online users to find most relevant content. When looking for information about any movie, music, video, the internet users come across a bewildering number of options to fetch precise data from the recommended list. The main goal of the recommender system is to suggest high quality and top rated videos to the user. However there exist thousands of video items said to be Long Tail (videos with least rating) that stagnate idle on the web server for years that are unrevealed by users because of its least rating. The new recommender system introduced in this paper uses rating based binning technique that favors not only top rated videos to get recommended, but also recommend Long-Tail videos. This can improve diversity on recommendation and suggest best long tail videos to the user. This implies that a least popular video has a high probability to become more popular when it is placed on the related video recommendation lists of popular videos. In order to evaluate the proposed video recommender system, the datasets are crawled from YouTube©, a well-liked online video community to suggest videos with high rating along with less rated long tail videos.

Title:	AN EFFICIENT ALGORITHM FOR CLUSTERING INTRUSION ALERT
Author:	ADELINA JOSEPHINE D, ANUSHIADEVI R, LAKSHMI NARAYANAN T R
Source:	Journal of Theoretical and Applied Information Technology pp 234 - 240 Vol 37. No. 2 -- 2012
Abstract	Intrusion Detection System is an emerging technology for detecting the unauthorized users and malicious behavior in a system. Alert supervision is tedious in intrusion system, so Meta alerts are created. Meta alerts are generated for appropriate clusters and they form a generalization of alerts. The objective is to identify origin of these alerts. In this paper, we propose a hybrid clustering algorithm which is applied to the data set to cluster the alert. Online alert aggregation is applied to this data which identifies the intruder .Redundant data are filtered during the process of clustering and aggregation, which substantially reduces the false positive rate. From the observed false positive, the origin of the alert are reduced.

Abstract	Email has become an essential communication tool in modern life, creating the need to manage the huge information generated. Email classification is a desirable feature in an email client to manage the email messages and categorize them into semantic groups. Statistical artificial intelligence and machine learning is a typical approach to solve such problem, driven by the success of such methods in other areas of knowledge management. Many classification methods exist, of which some have been already applied to email classification task, like Naïve Bayes Classifiers and SVM. Deep architectures of pattern classifiers represent a wide category of classifiers. Recently, Deep Belief Networks have demonstrated good performance in literature, driven by the fast learning algorithm using Restricted Boltzmann Machine model by Hinton et al, and the improvement in computing power which enables learning deep neural networks in reasonable time. Many datasets and corpus exist for email classification, with the most famous one is Enron dataset, made public by FERC, annotated and processed by many entities like SRI and MIT. In this paper, a machine learning approach using Deep Belief Networks is applied to email classification task, using the Enron dataset to train and test the proposed model.

Source:	Journal of Theoretical and Applied Information Technology pp 252 - 260 Vol 37. No. 2 -- 2012
Abstract	World Wide Web is useful source of information. Websites contains many web pages which automatically occupied by common template with contents. In former system, TEXT template extraction technique is used for template detection and also extract template from dynamic web pages, but it extracts the entire site and stores in database. It provides the unnecessary information for further processing. To overcome this problem, Vertex based information extraction technique is used, which would improve the web search results quality and web integration for dynamic web pages. To operate at web scale, Vertex employs a host of novel algorithms for web page clustering, robust wrapper learning, detecting site changes, and rule relearning optimization. The system is deployed in production and currently extracts millions of records from many websites, in order to get high efficiency. Vertex is the first system to do high accuracy information mining at web scale.

Title:	ENHANCING MINE SAFETY WITH WIRELESS SENSOR NETWORKS USING ZIGBEE TECHNOLOGY
Author:	P.RAGHURAM, VEERAMUTHU VENKATESH
Source:	Journal of Theoretical and Applied Information Technology pp 261 - 267 Vol 37. No. 2 -- 2012
Abstract	In coal mines, whenever explosions occur, the rescue work is done by rescue workers without any prior knowledge of the environmental condition inside coal mine because the mine monitoring systems may be destroyed or damaged. This makes the life of rescue workers very risky. It also takes some time for the rescue workers to reach the spot. According to the proposed system, a ZigBee network controlled automatic robot has been developed for assisting rescuers. This system works even when a ZigBee node fails. Whenever any explosions occur, the robot automatically detects the explosion, finds the explosion location and enters the coal mine tunnel well before the arrival of rescuers. It finds the location of accident, searches for survivors to give them first aid at right time and informs the rescue team about environmental conditions and about the survivors inside the coal mine.

Abstract	Current research efforts are being directed to commit with the long-term view of self-management properties for wireless telecommunications. One of the key approaches that have been recognized as an enabler of such a view is policy-based management. Policy-based management has been mostly acknowledged as a methodology that provides flexibility, scalability, adaptability and support to automatically assign network resources, control Quality of Service and security, by considering administratively specified rules. The hype of policy-based management was to commit with these features in run-time as a result of changeable network conditions resulting from the interactions of users, applications and existing resources. To detect and resolve potential static and dynamic conflicts between the rules and configurations from different administrative domains, a policy-based manager coordination PobMC framework which is based on Event- Condition-Action (ECA) is proposed in this paper. The framework is responsible of potential conflicts between applications included in the system. Furthermore, the paper provides a guideline to avoid policy conflicts between different domains configurations, and resolve the conflicts during runtime. PobMC depends on, static and dynamic analysis to reduce potential conflicts. The paper briefly outlines some of the most prominent research issues that have been discussed for large-scale adoption of policy-based systems. Then we present a description of the conflict detection and resolution algorithms that achieves the automated enforcement of obligations for resource-handling based on management policies.

Source:	Journal of Theoretical and Applied Information Technology pp 289 - 296 Vol 37. No. 2 -- 2012
Abstract	This paper at first presents a control algorithm for a single-phase grid-connected photovoltaic system in which an inverter designed for grid-connected photovoltaic arrays can synchronize a sinusoidal current output with a voltage grid. This paper presents modeling, controller design, and simulation study of a grid connected PV system. The overall configuration of the grid connected PV system is present. The main points discussed here are the MPP tracking algorithm, the synchronization of the inverter and the connection to the grid. Tracking the dc voltage and current allows MPP calculation which gives the inverter to function efficiently. We apply the MPP equations to the PV array model and watch the inverter input and output. In order to synchronize the simulated inverter to the grid the waveforms from the grid are applied to the pulse width modulation (PWM) input and drive appropriately the inverter’s IGBT’s. A Matlab/Simulink based simulation model is developed for the system. A Simulation results are presented to show the overall system performance.
